In South Carolina’s 1st congressional district, the open-seat contest between Republican Jenny Costa Honeycutt and Democrat Nancy Lacore remains closely balanced in trader pricing, with limited separation across margin buckets. The race follows Nancy Mace’s decision not to seek re-election and features recent primary runoffs plus an early-October debate. Available polling shows mixed but narrow results, including a Republican-sponsored survey giving Honeycutt a modest edge and a Democratic internal showing Lacore slightly ahead, consistent with the district’s historical Republican lean narrowing under current national conditions. Traders appear to weigh the candidates’ profiles, voter turnout patterns in coastal and suburban areas, and the absence of decisive late-cycle shifts that would widen the outcome. Scheduled events through early November could still influence final positioning before resolution.
